Referring to figs. 1 through Fig. 3, the structure and the action of execution mode of the present invention are described.In addition, in following execution mode, show the structure example of the situation of dynamic image as the example of content, but also can use identical structure in the situation of rest image, audio frequency, voice.
< execution mode 1 >
Fig. 1 is the figure of the syndeton of expression when using the related Femto cell gateway apparatus of an embodiment of the invention.As shown in Figure 1; Indoor 150; Home server 155, television set 157, DVD (Digital Versatile Disk; Digital multi-purpose disk)/HDD (Hard Disk Drive, hard disk drive) tape deck 158 directly is connected with Femto cell access point 200, or be connected with Femto cell access point 200 via in-home network.Here, Femto cell access point 200, home server 155, television set 157, DVD/HDD158 can be that benchmark connects with DLNA (DLNA) criterion for example.
Indoor Femto cell access point 200 is connected with the interior IP network 135 of local, is connected with mobile IMS network 130 via IP network.Moving IMS network 130 here, can describe with BB (broadband network) for BB (broadband network), NGN (next generation network), the Internet etc. below.
Femto cell gateway apparatus 110 is arranged on and moves on the IMS network 130, is connected with indoor Femto cell access point 200.
In addition, Femto cell gateway apparatus 110 is xGSN (serving/gateway General packet radio service Support Node (service/gateway general packet wireless service support node) with the packet transfer device, packet that is positioned on the mobile network 140; With SGSN (Serving General packet radio service Support Node; The service universal grouping wireless serving GPRS support node) and GGSN (Gateway General packet radio service Support Node; Gateway general packet wireless service support node) carry out the integrated node that forms) device 190 connections, carry out the transmission and the reception of packet.
In addition, be connected with portable terminal 170 via wireless base station 141 on RNC (radio network controller) device 195.
As the not special restriction of portable terminal 170, use mobile phone to describe below.
When portable terminal 170 connects,, and carry out authentication via mobile network's 140 accesses network (Web) server 120.
The webserver 120 outputs to Femto cell gateway apparatus 110 with the notice of authentication completion and the selection result of content, and notifies the reception IP address of Femto cell gateway apparatus 110 to portable terminal 170.
Then, portable terminal 170 sends connection request to Femto cell gateway apparatus 110.Below, the employed agreement of connection request is made as the HTTP (HyperText Transfer Protocol, HTTP) of TCP/IP, but also can uses SIP (Session Initiation Protocol, SIP) etc.
When using HTTP, portable terminal 170 can use request instruction to send connection request.
Fig. 2 is the figure of the structure of expression Femto cell gateway apparatus 110.Femto cell gateway apparatus 110 has control signal transformation component 111, packet acceptance division 112, transcoding device portion 113, file transformation component 114, protocol conversion portion 115, packet sending part 116, conversion indication portion 117 and capability list 118.
Control signal transformation component 111 obtains notice and the content choice result that authentication is accomplished from the webserver 120, receives the HTTP request instruction from portable terminal 170.
The terminal class information of control signal transformation component 111 through being put down in writing in user agent's head of reading the HTTP request instruction, thereby the terminal class at definite terminal 170.
As the not special restriction of terminal class information, for example, mobile phone manufacturer or form etc.And, terminal class information is outputed to conversion indication portion 117.
On the other hand, control signal transformation component 111 will be transformed to the for example Invite information of SIP (SIP) from the request instruction among the HTTP of portable terminal 170, be that target is sent with the reception IP address of Femto cell access point 200.
In addition, control signal transformation component 111 is transformed to the for example Info information of SIP with the content choice result, sends to Femto cell access point 200.
With reference to Fig. 1, Femto cell access point 200 receives SIP Invite information from Femto cell gateway apparatus 110, and offers dialogue once more.
In addition, Femto cell access point 200 receives SIPInfo information from Femto cell gateway apparatus 110, and to its video content of resolving and confirming to read, notice is given DVD/HDD tape deck 158.
In addition; Femto cell access point 200 is read the file of said content from DVD/HDD tape deck 158; With the content file of reading, use for example RTP (Real-time Transport Protocol, RTP) agreement; Via IP network 135 and mobile IMS network 130, send to Femto cell gateway apparatus 110.
If with reference to Fig. 2; Then the packet acceptance division 112 of Femto cell gateway apparatus 110 receives the packet of the content file of reading from DVD/HDD tape deck 158 from Femto cell access point 200; Extraction is stored in the data flow in the file of this content file, and to 113 outputs of transcoding device portion.
In addition; The content information of being stored in the packet acceptance division 112 reading of content files (for example the duration of the compression coding mode of the duration of the screen resolution of the compression coding mode of video, video, bit rate, frame per second, video content, audio frequency, audio content etc.), and to 117 outputs of conversion indication portion.
Conversion indication portion 117 obtains terminal class information from control signal transformation component 111, obtains said content information from packet acceptance division 112, confirms to carry out which kind of conversion by transcoding device portion 113.
For example; According to said content information; Identify the video content read from DVD/HDD tape deck 158 with MPEG-2MP (Main Profile, master ga(u)ge model), 8Mbps (mbit/) be compressed coding, screen resolution is that SD (720 * 480 pixel), frame per second are 30fps (frame/second).In addition, go out portable terminal 170 according to said terminal class information Recognition and be novel mobile telephone.
In conversion indication portion 117, in capability list 118, preserve corresponding to the terminal kind in advance
The codec that allows,
